NURSING BOTTLE.

Application filed May 14,

To all whom it may concern:

Be it known that I, WILLIAM MORE DE0K- ER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Nursing Bottles, of whichthe following is a specification.

This invention relates more particularly to the type of nursing bottles comprising a wide-mouthed food-cell or receptacle and an elastic cover or so-called breast-nipple having a dome-shaped body stretched over the mouth of the cell and terminating in a nip- P One of the objects of the invention is to providethe breast-nipple with simple means for reliably preventing its collapse or inversion into the mouth of the food-cell by the pressure of the infant or from nursing, and yet preserve the desired mobility of the breast-portion to permit it to roll freely in all directions, similar to the natural breast.

The invention has the further object to improve the construction of the food-cell with a view of rendering it more stable and facilitating the application of the breastnipple thereto.

In the accompanying drawings: Figure 1 is a sectional side elevation of a nursing bot tleembodying the invention. Figure 2 is a vertical section of the upper portion thereof, on an enlarged scale, showing the breast-nipple in its normal position. Figure 3 is a similar section showing the breastnipple partly collapsed. Figure 4 is a section-a1 elevation of the breast-nipple removed from the cell. Figure 5 is a bottom plan view of the food-cell.

Similar characters of reference indicate corresponding parts throughout the several views.

The wide-mouthed food-cell 10 shown in the drawings, has the customary straight or cylindrical body, but the same may be tapered upwardly, or of any other suitable form.

On the underside of its bottom, the cell is preferably provided with a stabilizing ring or base-rim 11 projecting a short distance below its body. This rin has a flat hearing face 11" and is nearly t e fully diameter of the cell, thus materlally increasing the stability of the cell and resisting rocking or tipping thereof in stretching the cover or breast-nipple 12 over 1ts mouth.

At its mouth, the cell is encircled by the 1923. Serial No. 638,797.

usual lip or projecting flange 13 under which engages the customary reinforcing rib or enlargement 14, at the base of the cover. The

latter, including the breast 15 and the nipple 16 is molded of soft rubber in the usual manner. As shown, the breast is comparatively thick to give it the desired firmness, while the portion 17 of the cover between its reinforcement 13 and the base of the breast is preferably reduced in thickness to render it more pliable than the breast and permit the latter to roll in imitation of the natural breast.

Surrounding the base of the brcast-portion is an external bead or stop 18 adapted to seat upon the portion of the cover stretched over the mouth of the food-cell, when'the cover is partly collapsed, as shown in Fig. 3. For this purpose, this stop-bead is of the proper diameter relative to the inside diameter of the cell-mouth. A

To guard against collapse or inversion of the breast-nipple into the mouth of theicell, i

especially when the breast is tilted tq' one,

When the breast is depressed by the infant,

the thinned lower portion 17 doubles on itself, and the internal bead is brought against the wall of the cell-mouth, as shown in Fig. 3, temporarily obstructing or reduc The location of this ining the diameter of the cell-mouth sufli 95 ciently to eifectually resist depression of the breast into the mouth. The internal bead is of sufficient thickness to effect this result and yet not so large in diameter as materially to interfere with the mobility of the breast. This bead may be of any appropriate diameter and cross section, and I do not therefore wish to be limited to the particular construction or dimensions herein shown and described.

The internal bead also serves as a circumferential stay or reinforcement for the thinned base-portion of the cover which resists undue enlargement thereof by repeatedly stretching it over the cell, thus lengthening the life of the cover.

As this internal head is an integral part of the cover or breast-nipple, these desirable features are obtained without increasing the cost of the cover: r

l claim as my invention:

1. A breast-nipple for a food-0e11,: having internal means arranged to enter and contract the mouth of the cell when the breast is partly collapsed, said contracting means being spaced from the upper end of the cell in the normal,uncollapsed condition of the breast-nipple.

; 2. A breast-nipple for a food-cell, provided with an internal bead arranged to rest.

against the inner Wall of the cell-mouth to reduee its diameter when thebreast is partly collapsed, and spaced from the upper end of the cell in the normal, uncollapsed condition of the breast nipple.

3. A breast-nipple for a food-cell, provided on its outer side With a stop arranged to seat against the base portion of the breast, when the latter is partly collapsed, andcon its inner side with means arranged to enter and contract the mouth of the food-cell in a partly collapsedieoudition ot' the breast, said inner-"contracting means being spaced from the upper end of the cell in the normal, uncollapsed condition of the breast nipple.

*inner wall of the cell-mouth to reduce its diameter, when the breast is partly collapsed,

2said internal bead being spaced from the upper end of the cell in the normal, uncollapsed condition of the breast nipple.

5. In a nursing bottle, the combination with a food-cell, of a breast-nipple provided internally with means arranged to contract the mouth of the cell when the breast is partly collapsed, said eontracting means being spaced from the upper end of the food cell in the normalQuncollapsed condition of the breast nipple.

6. In a nursing-bottle, the combination with a wide-mouth food-cell, of a breastnipple provided internally with a bead extending around the breast, said head being arranged to rest against the inner wall of the cell-mouth when the breast is partly eollapsed, and spaced from the upper end of the cell in the normal, uncollapsed condition of the breast nipple. n
